6 Claims. (Cl. 242122) The invention relates to improvements in ing ofthe spindle f the machine 130 which it iS spools and bobbins for thread,rayon, yarn, and applied, and it is therefore among other feathe like,as described in the present specification, tu es of t s invention tocombine all the efand illustrated in the accompanying drawing ec V 0fthe l t bobbin or Spool and add that forms part of the same. thereto allthe durability of the heavier bobbin The invention consists essentiallyin devising a P L in other y utilizing t e barrel spool in which thebarrel or cylinder may consist made from cardboard and adding thereto abase of a cardboard, paper, or other similar substance e from Wo d or elike, and devisin a means and in forming the base or bases for thebarrel for locking e tWO together SO that the barrel or cylinder of amore durable substance such as Will not D1111 Out in either e o theother direc- 10 wood and in looking the two together to complete tiOn, atrue balanced bobbin 1 0 s 0011- an integral spool, as pointed outbroadly and Structed, and in the pa ying drawing nd specifically in theclaims for novelty following a following de 'p an acceptable pe of p odescription in detail of an acceptable form of 'ut g t e locking featureis utilized.

Referring to the drawing, the spool or bobbin 15 Theobjects of the invention are to d vi consists of a tubular barrel memberas indicated satisfactory spinning and winding bobbin r by the numeralIII, which is made of suitable maspool for thread, silk, rayon, yarn,and the like, terial such as paper, cardboard or the combinawhich willbe both light and strong and will run tion o pape a d d d, a d one endof the true on account of being perfectly balanced; to barrel is flangedou w y t0 o m a generally 20 avoid vibration during the use of the spoolor onical flan e as indicated by the numeral H. bobbin and consequentlydecrease the wear of the The base is Preferably made o wood or ofspindle; to assure a better wound spool or bobbin other suitablesubstance heavier than the mateand thereby save a waste of time andthread, and rial of the barrel.

In the type of spool or bobbin asdescribed in Like numerals of reference indicate corre- Figures 5 and 6,the same construction is shown sponding parts in the various figures.with the exception that the head It of the spool It'is well known in theart to have wooden is shaped slightly differently fromthe base, and 50spools or bobbins but these are too heavy and also is provided with theorifice and a conical expensive for this purpose, whilst a spool madeseat I! for the purpose of engaging with the of all paper is not strongenough for this purflared ends 18 of the cardboard barrel l9.

It will be noted that the constructions shown and described will serveadmirably to accomplish the objects stated above. It is to beunderstood,however, that the constructions disclosed above are intended merely asillustrative of the invention and not as limiting as variousmodifications therein may be made without departing from the inventionas defined by a proper interpretation of the claims which follow.

What I claim is:

1. In a spool or bobbin, a tubular barrel formed of rolled cardboard orthe like, at least one end of which is formed with a generally conicalflared out flange, a base of wood, or the like, formed with a generallycylindrical orifice fitting upon the said barrel and a generally conicalseat extending outwardly from said orifice uponwhich seat the externalsurface of said flared out flange is seated, the outer end of saidconical seat being bounded by an orifice extending to the end of the vbase and a bushing of wood or the like fitting tightly in thesecond-mentioned orifice and having a conical end conforming to theinternal surface of said flared out flange on the barrel tube, whereby acomposite spool or bobbin is formed in which the barrel tube is firmlyinterlocked with the base and the' base and bushing entirelyenclose andconceal the end of said barrel tube. 1

2. In a spool or bobbin, a tubular barrel formed of rolled cardboard-orthe like, at least one end -of which is formed with a generally conicalflared out flange, a base of wood, or the like, formed with a generallycylindrical orifice fitting upon the said barrel and a generally conicalseat extending outwardly from said orifice and ,upon which the externalsurface of said flared out flange is seated, the outer end of saidconical seat being bounded by an orifice extending to the end of thebase, and a bushing of wood or the like fitting tightly in the secondmentioned orifice having a conical end conforming to the internalsurface of said flared out flange on the barrel tube and having itsouter end in the plane of the outer end of the base, whereby a compositespool or bobbin is formed in which the barrel tube is firmlyinterlockedwith the base and the base and bushing entirely enclose and conceal theend of said barrel tube. and form a continuous end surface of wood orthe like.

3. In a spool or bobbin, a tubular barrel formed of rolled cardboard orthe like, at least one end of which is formed with a flared out flange,a base of wood, or the like, formed with a generally cylindrical orificefitting upon the said barrel and a seatextending outwardly from saidorifice upon which seat the external surface of said flared out flangeis seated, the outer end of said seat being bounded by an orificeextending to the'end of the base, and a bushing of wood or the likefitting tightly in the second mentioned orifice and having an endconforming to the internal surface of said flared out flange on thebarrel tube, whereby a composite spool or bobbin is formed in which thebarrel tube is firmly interlocked with the base and the base and bushingentirely enclose and conceal the end of said barrel tube.

4. In a spool or bobbin, a tubular barrel formed of rolled cardboard orthe like, at least one end of which is formed with a flared out flange,a base of wood, or the like, formed with a generally cylindrical orificefitting upon the said barrel and a seat extending outwardly from saidorifice upon which the external surface of said flared out flange isseated, the outer end of said seat being bounded by an orifice extendingto the end of the base, and a bushing of wood or the like fittingtightly in the second mentioned orifice and having an end conforming tothe internal surface of said flared out flange on the barrel tube andhaving its outer end in the plane of the outer end of the base, wherebya composite spool or bobbin is formed in which the barrel tube is firmlyinterlocked with the base and the base and bushing entirely enclose andconceal the end of said barrel tube and form a continuous end surface ofwood or the like.

5. In a spool or bobbin, a tubular barrel formed of rolled cardboard orthe like, at least one end of which is formed with a generally conicalflared out flange, a base of wood, or the like, formed with a generallycylindrical orifice fitting upon the said barrel and a generally conicalseat extending outwardly from said orifice upon which seat the externalsurface of said flared out flange is seated, the outer end of saidconical seat being bounded by an orifice extending to the end of thebase, and a bushing of wood or the like having a orifice, the bushingbetween the parts mentioned being formed to conform to the internalsurface of said flared out flange on the barrel tube, whereby acomposite spool or bobbin is formed in which the barrel tube is firmlyinterlocked with the base and the base and bushing entirely enclose andconceal the end of said barrel tube.

6. In a spool or bobbin, a tubular barrel formed of rolled cardboard orthe like, at least one end of which is formed with a flared out flange,a base of wood, or the like, formed with a generally' cylindrical,orifice coaxial with said barrel and a seat extending outwardly fromsaid orifice upon which seat one surface of said flared out flange isseated, the outer end of said seat being bounded by an orifice of largerdiameter than said first mentioned orifice, and a bushing" of wood orthe like fitting tightly in the second mentioned orifice and having anend conforming to the other surface of said flared out flange on thebarrel tube, whereby a composite spool or bobbin is formed in which thebarrel tube is firmly interlocked with -the base and the base andbushing entirely enclose and conceal the end of said barrel tube.
